Purpose: The purpose of this study was to investigate the association of generalized aggressive periodontitis with IL-6 promoter gene single nucleotide polymorphisms(SNP). Material and Methods: The study population consisted of 52 generalized aggressive periodontitis patients(GAP) and 30 periodontally healthy control subjects, who were systemically healthy non-smokers. Genomic DNA was obtained from buccal swab. The IL-6 promotor SNP at the positions of -597, -572, and -174 were genotyped by amplifying the polymorphic region using polymerase chain reaction(PCR), restriction enzyme digestion and gel electrophoresis. Result: The genotype distributions for G/G, G/A and A/A genotypes of IL-6 -597 were 30.8%, 40.4%, and 28.8% in the GAP group and 53.3%, 40%, and 6.7% in the control group and were statistically different between 2 groups(p<0.05). Allele 2 frequency of IL-6 -597 were significantly higher in the GAP group than the control group(p<0.01). At the position of IL-6 -572, the distribution for C/C, C/G and G/G genotypes were 23.1%, 55.8% and 21.2% in the GAP group and 20%, 33.3%, and 46.7% in the control group. In female subjects, the genotype distribution were significantly different between 2 groups(p<0.01). In male subjects, allele 2 frequency of IL-6-572 was significantly lower in the GAP group than the control group(p<0.05). The genotype distribution of IL-6 -174 in the GAP group were 96.2%, 3.8% for G/G, G/C genotypes whereas only the G/G genotype was detected in the control group. Conclusion: In conclusion, significant associations were found in IL-6 gene promoter(-597, -572) polymorphisms and generalized aggressive periodontitis. Further cohort study will be necessary in larger population.

Background Herbal prescriptions have various effects and their efficacy is potentiated by the use of combinations of medicinal herbs. Objective Jageum-Jung (JGJ) is a traditional oriental medical prescription composed of five herbs. It has been used for detoxifi cation, and as an anti-inflammatory and antitumor agent. However, the effect of JGJ on hepatic fibrogenesis is unclear. Results We investigated the role of JGJ in TGF-β1/smad signaling, which is implicated in fibrogenesis, and its hepatoprotective effect in CCl 4 -treated mice with liver fi brosis. Treatment of LX-2 cells with TGF-β induced expression of mediators (α-SMA, PAI-1, and MMP-2) of fibrogenesis and activation of proinflammatory cytokines (TNF-α, IL-1β, and IL-6). However, these were downregulated by pretreatment with JGJ. In mice, oral administration of JGJ prevented liver injury induced by CCl 4 , as indicated by decreases in the ALT and AST levels. Conclusions JGJ inhibits hepatic fibrogenesis and TGF-β1/Smad signaling.

<P>We performed this study to investigate the feature of rejection in porcine-to-rat corneal orthotopic transplantation and to evaluate the effect of cyclosporine and mycophenolate on the xeno-rejection. Orthotopic corneal transplantation was done at 91 Sprague-Dawley rats, and they were divided into 10 groups based on the combination of immunosuppressants including dexamethasone, cyclosporine, and mycophenolate mofetil. Graft survival was analyzed and grafted eyes were examined with Hematoxylin & Eosin and CD4 or CD8 staining. Enzyme-linked immunosorbent assays were done for interleukin-2 (IL-2), IL-4, IL-5, IL-10, and interferon (IFN)-γ in cornea, lacrimal gland, and cervical lymph nodes. The longest median survival of the immune suppressant group was 11.00±1.96 days, which showed no statistical differences compared with that of control (8.00±1.52 days). The neutrophils were prominent in the early phase but soon gave way to the monocytes. The number of CD8+ cells was higher than that of CD4+ cells. IL-2 and IFN-γ markedly increased at 10 to13 days in cornea, lacrimal glands, and cervical lymph nodes, which showed a decrease with immunosuppressants except in the cornea. In conclusion, cyclosporine and mycophenolate could not prevent the rejection in porcine to rat orthotopic corneal xenograft associated with infiltraton of CD8+ and innate immune cells.</P>

Myristicin은 육두구에서 발견되는 고농축 정유 중 하나인 물질이다. 하지만 Th1/Th2 면역반응에서 육두구의 항알레르기 효과는 아직 밝혀지지 않았다. 최근에 Th1/Th2 전사인자로서 T-bet, GATA-3가 밝혀졌는데 이번 실험에서 myristicin이 ovalbumin(OVA)으로 유도한 천식(asthma) 생쥐모델에서 Th1,Th2 싸이토카인과 유전자 발현을 조절할 수 있는가에 대하여 알아보았다. 또한 기관지 폐포 세척액을 회수하여 백혈구의 수적 변화, 제2형 협조T세포(Th2 cell)가 생산하는 IL-4, IL-5의 생산에 미치는 영향과 폐조직에서 matrix metalloproteinase (MMP)-9 활성을 측정하였다. 그 결과 기관지 폐포 세척액에서 OVA로 감작하여 천식을 유도한 실험군에서는 호산구의 현저한 증가, Th2 형 싸이토카인(IL-4, IL-5)의 증가가 관찰되었다. 그러나 myristicin을 투여한 그룹에서는 OVA의 감작에 의하여 증가한 각종 염증성 지표들이 감소하거나 정상화 되었다. 또한 OVA에 의하여 증가된 기도저항성이 myristicin 투여에 의하여 감소하였으며 폐조직의 염증성 소견도 뚜렷하게 감소되었다. 이와 같은 연구 결과는 myristicin이 천식의 치료에 유용하게 쓰일 수 있음을 시사해준다. Myristicin, l-allyl-3,4-methylenedioxy-5-methoxybenzene, was one of the major essential oils of nutmeg. However, its anti-allergic effect in the Th1/Th2 immune response was poorly understood. Recently, it was shown that T-bet and GATA-3 was master Th1 and Th2 regulatory transcription factors. In this study, we have attempted to determine whether myristicin regulates Th1/Th2 cytokine production, T-bet and GATA-3 gene expression in ovalbumin (OVA)-induced asthma model mice. Myristicin reduced levels of IL-4, Th2 cytokine production in OVA-sensitized and challenged mice. In the other side, it increased $IFN-{\gamma}$, Th1 cytokine production in myristicin administrated mice. We also examined to ascertain whether myristicin could influence eosinophil peroxidase (EPO) activity. After being sensitized and challenged with ovalbumin (OVA) showed typical asthmatic reactions. These reactions included an increase in the number of eosinophils in bronchoalveolar lavage fluid, an increase in inflammatory cell infiltration into the lung tissue around blood vessels and airways, and the development of airway hyper-responsiveness (AHR). The administration of myristicin before the last airway OVA challenge resulted in a significant inhibition of all asthmatic reactions. Accordingly, these findings provide new insight into the immunopharmacological role of myristicin in terms of its effects in a murine model of asthma.

( Jung Ho Choi ),( Hye Mi Jin ),( Moon Ju Kim ),( Young Nan Cho ),( Kwang Il Nam ),( Seung Jung Kee ),( Jang Bae Moon ),( Dong Jin Park ),( Yong Wook Park ),( Shin Seok Lee ),( Tae Jong Ki ) 대한내과학회 2013 대한내과학회 추계학술대회 Vol.2013 No.1

Introduction: MicroRNA-155 (miR-155) is crucial for the proinflammatory activation of human myeloid cells and antigen-driven inflammatory arthritis. Since, the functional role of miR-155 in gouty arthritis has not been defined. The aim of this study was to examine the role of miR-155 in pathogenesis of gouty arthritis. Materials and methods: Samples from fourteen patients with gouty arthritis and ten healthy controls were obtained. Monosodium urate (MSU) crystals were prepared by recrystallization from uric acid. Total RNA was isolated using the miRNeasy kit (Qiagen). The miScript Reverse Transcription Kit (Qiagen) was used for cDNA preparation. MiScript primer assay (Qiagen) were used for semiquantitative determination of the expression of human miR-155. Human TNF-α and IL-1β in supernatants were measured by Luminex (Millipore, USA) according to the instructions of the manufacturer. Gout peritonitis mice (Male C57BL/6J) model used to analyze expressions of miR-155, Src homology 2-containing inositol phosphatase-1 (SHIP-1), and inflammatory cytokines. Results: The samples from gout patients proved to be highly enriched in miR-155, with levels of expression being 4-fold higher than those found in peripheral blood mononuclear cells (PBMC) from healthy controls and gout (p<0.05). miR-155 was found to be strongly induced by stimulation of MSU crystals after 24 hours and their expressions gradually decreased. Stimulating with MSU crystals for the indicated times, and the level of SHIP-1 was found to be gradually decreased in according to over-expression of miR-155. miR-155 promoted MSU-induced proinflammatory cytokine production. Commensurate with our observations in human synovial monocytes, miR-155 expression was elevated in gout mice model. SHIP-1 protein levels were markedly reduced in cells by MSU stimulated, compared to the control. MSU crystal induced peritonitis mice significantly increased the production of inflammatory cytokines, such as TNF-α and IL-1β. Conclusion: Overexpression of miR-155 in synovial fluid mononuclear cells (SFMC) led to down-regulation of SHIP-1 and an increase in the production of proinflammatory cytokines.

Lee, Eun-Gyeong,Lee, Sang-Il,Chae, Han-Jung,Park, Seoung Ju,Lee, Yong Chul,Yoo, Wan-Hee Kluwer Academic/Plenum Publishers 2011 INFLAMMATION Vol.34 No.5

<P>To determine the effects of adrenomedullin (AM) on interleukin (IL)-1관-induced proliferation of rheumatoid synovial fibroblasts (RASFs) and production of matrix metalloproteinases (MMPs), cyclooxygenase (COX) and prostaglandin E2 (PGE2) by RASFs. The RASFs proliferation was evaluated with CCK-8 reagent in the presence of IL-1관 with/without AM (1-52) and AM inhibitor (AM (22-52)). MMPs, tissue inhibitor of metalloproteinase (TIMP-1), COXs, PGE2 and intracellular mitogen-activated protein kinase (MAPK) signalings, including p-ERK, p-p38, p-JNK were examined by immunoblotting or semiquantitative RT-PCR and ELISA. AM (1-52) inhibited IL-1관-induced RASFs proliferation and inhibited MMP-1, 3, COX-2 and PGE2 production. AM (1-52) also inhibited IL-1관-induced phosphorylation of ERK-1/2, p38, JNK. AM 22-52 inhibited the effects of AM (1-52) on proliferation of RASFs and production of MMP-1, 3, COX-2 via MAPKs. These results suggest that AM might involved joint destruction in rheumatoid arthritis and indicate that it might be a new therapeutic modality for management of this disease.</P>
